Get your taxes done using TurboTax

I am do tax for free to my relative and my niece and they all very short forms because they just start working dependently and I try to help them to file income taxes. I did about 7 income taxes include my and I can only file 5 E-filed but 2 of the income taxes rejected by the code error IND-525 and I just wonder can I do income taxes on the IRS website.
