In the Schedule K-1 step-by-step, how do I even know if I have U.S. bond interest included in Boxes 1 and 2A on my K-1? Where would I look for these? If I knew, the amount would be deductible on my state taxes. I am merely transferring numbers from my Trust Beneficiary Schedule K-1. I have the completed 1041 trust taxes as well as my 2020 Combined Forms 1099 that were used to complete my trust taxes.
