Get your taxes done using TurboTax

Hello this a silly question to ask, I wanted to see if I can go through the Turbo tax and try to see if I can get through it on my own, My Taxes are done, but I think I want to see if I can run through to see if I get something different, my tax person maybe left out some things, will I be able to go through the whole thing even though I already filed ??? Ive tryed going to the person myself and they brushed me off, wanted to , wanted to see for myself. Thanks

 

Need help !!!!!
