Get your taxes done using TurboTax

Would that mean that I enter my 20% and the "main" persons SSN and enter 60% since that is what we agreed on? (someone else is getting the remaining 20%)

 

Or do I enter it as I get 20% and they get 80% since I can only add 1 more person. They already filed their taxes in person but I do not want my mistake to affect them.
