Is your aunt due a refund? If so, are you the personal representative of her estate?
A POA is void upon the death of the principal (that would be your aunt).
You might want to read through IRS Publication 559.

sorry for your loss. you file form 1310.

read the instructions on where to file.
with Turbotax you can not e-file the form.

If your aunt died in 2021 and did not receive the third of the Economic Impact Payments, she may be eligible for the 2021 Recovery Rebate Credit if she met the eligibility requirements while alive. You will have to file a tax return for your aunt in order to receive the credit as a tax refund. The person in charge of the estate is responsible for making sure the tax return is filed. This could be the executor, spouse or anyone else in charge of the decedent’s property.
Thank you very much. That is what my turbo tax software is saying. Just wanted a second opinion.
