Get your taxes done using TurboTax

We fill out a check authorization form so that we can cash the check on their behalf so we are the middle man so we can get our portion before the client gets it. Our largest concern is that we may deposit $12,000 but we only keep $2,000 just wondering if we need to make a paper trail with the tax forms? So Critter#2 should the client be sending us a 1099? How do we show the monies we received?
