According to the OP, the next button is still grayed-out (not clickable) after you typed the address.
It simply means that there's something wrong with the address' format or you missed a character during copying/typing.

there are only two reasons why the next button is greyed out. one of them is what you said here, an error in the address itself when typing it in but also if you choose a different option and then enter an irrelevant data in it, then wallet won't let you move ahead.
for example if you choose recovery with seed but enter a private key there instead of your seed words.
since the second line in OP's comment doesn't make sense I say he chose a wrong path like this:
Standard wallet > Use public or private keys >
and then entered his address there.
he needs to choose the following path:
Import bitcoin addresses or private keys >
then enter his address
