Get your taxes done using TurboTax

Your gross receipts (from your 1099) will be entered on Line 1 of Schedule C (see screenshot below). 

It appears as if you may be trying to prepare the forms manually (just a guess) but, if that is the case, I would strongly urge you to use TurboTax (or some tax preparation software) since manual form preparation by the inexperienced can be replete with errors.
