Income from US obligations for state tax return

I had income from US obligations in 2024.  Some is from treasuries, and those amounts are helpfully on the 1099s.  Some is from agencies, which is not on the 1099s., but I think I know the amounts.   Anyway, I finished my federal, started state, and it said that I had income from US obligations in an amount that seems way too high.  I added up income from treasuries and agencies, and it's about half of what TT thinks.  So either I'm computing wrong, or TT made a mistake.
