We sold our main home last year. On this same property, there were 2 large buildings (separate from the house) that we rented out. It's my understanding that we must treat the sale as if two separate pieces of property were sold, reporting the business portion on form 4797, and the personal portion on form 8949. Unfortunately, TurboTax allows for no way to reconcile this when we enter our 1099-S, which only reports the total sale price of the property. Do I enter the amount reported on form 4797 as an increase to the basis of the personal portion to offset it? If I don't, this amount is reported twice, and the net gain is incorrect.
