@viceola A Form 1095-B is not entered on a tax return. Only a Form 1095-A is reported on a tax return
If your Form 1095-A shows a 0.00 in all the boxes for October thru December, leave those boxes blank (empty) when entering the 1095-A in TurboTax.
Why do you think you need to prove you had health insurance for Oct - Dec 2023 when you were on Medicare.
