You can't file a tax return for your father for 2022. You could file a return for his estate, but this is needlessly complicated. An estate is a separate legal entity. If you want to report the income as being to the estate, the estate needs a new tax ID number (can't use the decedent's SSN) and the 1099 would have to be re-issued with the tax number of the estate. Then, the estate files a form 1041 estate tax return (not a form 1040) and this requires a special version of Turbotax.
If you are the sole heir, the easier thing to do is to report the income on your 2022 return. It would be reported under Sale of stocks and other investments, in the category of "other investment" (don't use "your house" because that is only for a home that you occupy as your main residence).
Because you are filing your 2022 return late, and if you owe a tax payment, expect to be billed for a penalty and interest of about 50% of the amount of tax you owe. I would decline any suggestion in Turbotax to calculate an estimated penalty and include it with your return -- wait for the IRS to bill you. When you get the penalty notice, you can ask for a waiver for cause. The interest can't be waived, but if the penalty is removed the interest will be recalculated lower. (It's harder to ask for a waiver if you've already paid the penalty with your tax return.)
