State tax filing

2021 TT also led me to believe that Iowa taxes due equal zero. non-resident with IA income. Spoke to the IOWA tax support this morning and they confirm the numbers don't add up. IA form 126 for income did not have the correct calculations although the income was present on the 1040. I've been burned by this before. TT needs to audit this income vs minimum income tax exemption they tried to hand me.
