Get your taxes done using TurboTax

I have read this string 3 times and tried to do this and having some success but not completely.  I have the Home and Business download.  I probably sold tickets to 20 games, is someone suggesting that you need to list out each one with proceeds and cost, similar to what you do for 1099-b stock/bonds???  I just assumed I could bunch these.

One of the things I am having a problem correcting is the expenses incurred.  I put in a placeholder number thinking I could go back and update but can't figure out how to do that!  Tried via forms as well.

And two additional questions:

1- does anyone know what TurboTax does with the amount one types in when it asks how much is incorrectly reported (not ticket sales) as I still seem to see the gross amount and not the gross less what i said should be taken out.

2- separate from TurboTax, anyone have any clue what number TurboTax adds to your MAGI?  I was assuming it would be the profit that gets reported but since I can't enter it yet don't see where it is flowing and really hoping it is not the gross amount!  Thanks for any insight you may have.
