Houseplant, if I remember correctly, IRS form 1310 is the one used to file for a refund on behalf of someone else, so that the IRS can send the refund directly to you.
I'm really glad the step-up issue was addressed with your accountant.
First thing I would do is consult an elder law or tax attorney to address the issue of step-up value. At one time I was more familiar with this than I am now and wouldn't want to offer incorrect information. And there may have been changes in the recent tax law as well.
This might help (or given the nature of IRS publications, it might confuse) in understanding step-up issues. But the best source is a practicing professional accountant familiar with step-ups.
Step-up basis will be applied to my upcoming tax preparation. I've asked my tax agent about this after reading IRS information per your suggestion.
An unrelated item caught my attention while exploring the IRS site:
Refunds were always deposited into our joint checking account. I just realized I need to notify the tax preparer this account no longer exists.
A refund, if due, will otherwise be returned to the IRS as Undeliverable. IRS can not issue a refund if the bank account on record no longer exists. Incorrect information to the IRS would likely complicate tax filings/refunds moving forward for a long time.
