Get your taxes done using TurboTax

 ROTH contributions  are  NEVER dedictible on the tax return  and entering the contributions in the program is not sent to the IRS thru the tax return ... that info is sent via the form 5498 issued by the IRA custodian.  The reason to enter it in the TT program is so that the program keeps track of the contribution  AND  to calculate any possible Saver's Credit form 8880 ... so is that what you are referring to changing each year ?
