My "Federal due" doesn't change whether I add or remove taxable income/capital gains. Have maxed out $3K loss so expected the federal due should change with additional income but it stays the same. I can go all the way to ready to file and have turbo tax recalculate and check everything but the Federal Due remains as. Cannot figure out why.
