A few (basic) comments and I am sorry for your loss:
A federal estate income tax return (1041) will not be required unless the estate has income of $600 or more.
See https://www.irs.gov/instructions/i1041#en_US_2022_publink1000285942
The 1310 should result in the check being made payable to you, as personal representative.
Depending upon the financial institution, you may not be able to deposit the check that is made payable to the Estate in your personal account.
You will most likely have to print and mail the final return for your sibling next year as the SSN will be locked, but you can indicate that your sibling passed prior to the filing of the return in the TurboTax program.
