I am sorry to hear about the recent passing.
Here is an article regarding filing a return for a deceased taxpayer:

You may file a joint return in 2023. Make sure to report his social security benefits.
You can also report the medical expenses in the deductions and credits section of TurboTax, to see if you have enough itemized deductions in the tax return that exceed the standard deduction. 7,000 may not be enough to move into itemized deductions unless you have a lot of mortgage interest and real estate, and vehicle property taxes to report.
Thank you,
