You file as normal. Just indicate that you do not want to pay your taxes through TurboTax (pay by check) when asked how you want to pay your federal taxes (this question appears in the File section).
I just spoke to someone from Turbotax regarding this. She had me select the option to pay with a check instead of your option. Do I need to send paper work to the IRS?
Paying by check is the same as not paying through TurboTax. You do not need to send any additional paperwork in unless the program told you to. You can visit <a rel="nofollow" target="_blank" href="https://www.irs.gov/Payments">https://www.irs.gov/Payments</a> to make your payment.
