Hello Judi Gee.
Welcome to Microsoft Community and we are here to help.
For your handwriting option, you may need to reconfigure this option if you reset. You can reconfigure handwriting recognition by searching Cortana for Control Panel then find Clock, Language and Region> Language > choose "options" for your language > Personalize Handwriting Recognition.
If the issue is not resolved, you can contact Support here.
If you are in the United States, it is also advisable to visit the nearest store in your area to further check your Surface Pro 4.
Best regards.
