Sure the 0 isn't an O, Q or perhaps U? However even then I don't know that I've ever heard of a product key starting with either of these.
Another thing to consider is that a while back Windows 10 moved to a digital license such that it is tied to your MS account and not a product key. Not sure if that applies here.
Yet another thing to consider is that if you got your Win 10 license as part of a pre-purchased device then you got an OEM license. OEM licenses (recently) don't allow you to use the license on another machine at all. This prevents you from transferring the license from an older machine that you bought to a newer machine that you might have built. It is unfortunately but MS has to make money somewhere I guess.
Still, given your error it seems like you're entering the wrong letter.
