Get your taxes done using TurboTax

I sold a tractor.  The business use varied over the years.  I know the average historical % business use of the asset.  Hence I can generate the correct values for Lines 20 thru 25 of page 2 of form 4797 but cannot find a way to enter it step by step.  Is there a way to generate an enterable 4797 page 2 that links to Form 4797 page 1 and delete the other 4797 page 2 generated by step by step?  Thank you.
