Where do I find my distribution lists in the new Outlook.com?

I don't see the word "All v"

The word Manage is misleading. It does not really " manage " groups as you and I would think.

Here is the list of instructions I composed for users  about Groups :

How to create a group :

Go to People window > toolbar at top, click Manage > click Manage groups > click the plus (+) sign, a new box will appear, enter a name for the new group > click Apply > a new group is created.

How to access a group :

In the People window, near top left, click at the word " All v " > a drop down box will appear with a list of your groups > click the one you want > all the contacts within that selected group are now on the left side > scroll to see the whole list.

How to add contacts to the group you have created :

Still in People window > click a contact you want to be added to the group > if you have multiple contacts to add, click the box at top left of the contact > continue clicking the top left box of each contact you want to add to the group until you are done> at the toolbar, click Groups > check the box in front of the group name > click Apply > all the contacts you have selected are now in the group.

Note : make sure you click squarely at the check box. If you click outside the box, all previous boxes you have checked will be nullified, and you’ll have to start all over.

How to delete a contact from a group but keep it in the main contact list:

Go to People > click the contact you want to remove from a group > toolbar, click Groups > un-check the box in front of the group in question > click Apply when done.

How to Edit contacts within a group

On the People window, top left, click the “ All v “ > you group is on the drop down list > click the group name > now you have all the contacts within that group listed > click one to view > to edit, click at the contact’s name ( not its check box ) > click Edit at the toolbar to do editing......

Note : Edit option only appears at the toolbar after you have selected a contact.

I think they meant to click "Lists".

Unfortunately, the whole interface is quite a mess, and it's a wonder Microsoft is still in business.

I assume that when you created the distribution lists, you gave each list a name. It is called Group now.

How to access your groups :

Go to People window > in the People window, near top left, click at the word " All v " > a drop down box will appear with a list of your groups > click the one you want > all the contacts within that selected group are now on the left side > scroll to see the whole list.

Lists is under the dropdown that allows sorting of people/contacts.
