We're waiting on form IA148. It is now 15 March 2024 and the usable form has STILL not been ported to TurboTax. Mid-March is pretty late in the year for tax forms to not be finalized. We're going to file Federal then file state whenever they get their act together.
It is now March 26th and the Iowa Department of Revenue says there is no reason from their end that TurboTax should not have the useable form 148. It seems impossible to get to a live person at Turbo Tax to complain.
