electric filing with form 479

Please clarify how you entered the sale of the rental property. Did you use the Step-by-Step interview or did you fill out the forms manually?

I did step by step.  When I reached the rental income section,  I went o my items depreciated which I edited each asset and marked the sold area with the sale price fr each asset.  The gain, per TurboTax was then transferred to form 4797 to 1040.   However, turbax will not let me Efile saying that form 4797 (lines 19a, 20, 21 and 22 were overwritten which I did not do and cannot correct the error.  Thank you
