I am amending my 2023 Tax return. Is there a way to see what contributed to the change in 1040-X line 10: "Other taxes"?

I'm using the desktop version. The only thing I added was a 1099R form, that has federal tax witholding along with taxable amounts. The net change on that line, column B, doesn't match any dollar values from my 1099R form.

Box 10 of the 1040-X is Other taxes.  This is shown on Schedule 2 Line 21.

Check this form in your amended tax return.
