Are you an Iowa resident? How, exactly, did hundreds of sales get transferred from your federal return to your Iowa return?
Texas resident. I have a Schwab ETF "Intelligent Fund" that makes numerous ETF sales /purchases. Each one of these transferred to the Iowa return individually in addition to capital gains/losses from my K-1's. I went to Forms and just marked them all as exclude. Fastest way. I did 14 other state returns primarily for LLC partnerships and didn't have thus happen
