I'm very sorry for your loss.
You should indicate that your spouse died in 2021 so that "deceased" will appear on his 2021 tax return. You can enter your information in TurboTax and if it qualifies as a simple return you will not be charged for it. You do no pay for the return until you are finished and ready to file it, so you don't have to pay unless you decide to file the return prepared in TurboTax.
