Retirement tax questions

Yes, report the medicare payments minus the refund you received on your SSA-1099 which will carry to itemized deductions if you use that instead of the standard deduction. It is handled this way because the payment and refund occurred in the same tax year.

If  you choose  you can also use the 'Lump Sum' election if you received any social security benefits in 2024 that actually apply to 2023. It may not apply since the application was in 2024, however if  you did receive any benefits in 2024 for a prior year you can use it.

Be sure to select "lump-sum" method of reporting in this situation which is all done on the tax return for the year of receipt of the benefits.  Enter the appropriate amounts for each year when you start that section of your return.   Continue to add each year for all years listed in box 3. There is no amendment required.
