Deductions & credits

This just complicated fast. I now see that my spouse's last paycheck also was not reported on the correct form since it was included on the W-2 with all the other wages, but it came after death. So, it, too, should have been reported on a 1099-MISC. But, I already filed those taxes last year. Can I still do something about that? Do I need to get the employer to do something for the 2022 income and file an amended return or something?

I also don't see that TT filed a 1041. It was a 1040-SR, I guess because my spouse was 65. We had a revokable trust together, married many decades, and live in AR. I got everything. So, was I supposed to file a 1041?
