I am getting this same error for the 2022 tax year. "Turbotax Form 7203 error message says Line 3g cannot have a gain in Part I and a loss in Part III." The only way to "trick" the program is to show Part III Current Year losses and Deductions (Column a) as Column b amounts (Carryover amounts from the previous year). I know this is not the right solution and will likely create questions with the IRS when I e-file. The fact is that I DO have Net Capital Gains to show in Part I, line 3g, as well as losses in Part III.
Any thoughts?
