Just to further clarify, I'm just relating how I did it & not advising anyone on the 'right' way, etc. It's true you don't actually end up writing out your signature - it gives you a number & calls it the digital signature. DH never filed or signed forms anyway, as he's an NRA & not a US person so doesn't feel obliged to do so. Right, wrong, or indifferent. They have the account details & his name, we're married & at same address. <shrugs>
Left the SSN/TIN space blank as he doesn't have one & field will only accept numbers. The space says input it 'if known' - the form was accepted without it. I added a notation beside his name that he's a Non Resident Alien & it accepted that. In any case, it'll match the preceding 8 years' worth I've already filed.
If we get much more reno work done on the house, those funds are going to be quickly depleted. So I'm doing my best to get that money spent, lol!
