You can do what you want, obviously. Now I'm not trying to scare you or anything here. A lot of folks make mistakes on their returns and never get audited or called out on it by the IRS. Just keep in mind that as far as the IRS is concerned, you, and only you are responsible to the IRS for the accuracy of your return. Not TurboTax, and not a CPA from the IRS perspective.
While TurboTax does offer a 100% Accuracy Guarantee, that only pays your fines and penalties when assessed. You are still responsible for any additional taxes. If you get audited, and you haven't pre-paid TurboTax for Audit Defense, it can (and will) get costly. But even with Audit Defense, you are still responsible for any additional tax that may be due, from an audit.
