Help please.

gain on 3 paid parcels exceeds the $500,000 exclusion

if I enter all 4 parcels on Home Sale Worksheet and check the 6252 installment sale box on Home Sale Worksheet it throws everything to 6252.... doesn't seem correct to then enter principal received for the 3 paid parcels

Can I just enter the 3 paid parcels on Home Sale Worksheet and the land contract parcel on 6252 since the exclusion is used on the 3 paid parcels

I need a nap.
