Better to file with IRS using a POA or a bad quality signature?

[Cyrribrae]

Trying to file for a person for whom I have a POA (but not a 2848). Had a medical incident last year. We started a paper return at the time while he was still almost entirely incapacitated (out of uncertainty with how to efile), but he has recovered enough now to be able to somewhat sign his own name poorly. It's not particularly recognizable and it certainly wouldn't match any previous years'.

If he were to sign the document himself, are there any other documents that I should include with the return? An explanation of the signature? Our POA anyway?  Or is the best bet to use our POA to fill out a 2848 and sign myself?

Thanks!

Yes, if you have a valid Power of Attorney, you can use TurboTax to file your father's return - either by mail or e-filing.  Per @ToddL99

TurboTax files the returns electronically, so there is no actual signature on the returns there are self select pins that he can choose himself and file is return himself.

You may want to submit a form 2848 to IRS electronically after you file to be able to receive information directly on this client.
