The US govt interest to be deducted should be coming from the total of
1) box 3 $$ on 1099-INT forms
and
2) the US Govt interest you indicated as a sub-part of box 1a $$ on 1099-DIV forms.
_______________________
For #2, you EDIT the 1099-DIV form, and enter all the $$$ that are actually on your real 1099-DIV.
............THEN..you Continue to the next page and there is a checkbox to select:
"A portion of these dividends is U.S. Government interest."
......THEN..you continue to the next page you get to enter what sub-part of box 1a represents $$ received as US Govt Interest....and those $$ should then added in with #1 to go into line 10 of the MI schedule 1.
...BUT...you have to calculate the proper amounts yourself, since the value in box 1a and a 1099-DIV can be a mix of stock dividends, Mutual Fund short term gains, and other mixed Corporate/US Govt bond dividends.

I suspect there may also be some US Govt $$ that can come in on a form K-1...but I have no experience with that particular form
