Get your taxes done using TurboTax

So i paid $2,96.40 in Medicare prem.  my husband also pad the same, so that = $4,192.80 before i even start to write in my co-pays and Rx's for the year.  Turbo tax, won't even let me get to that screen, and i have all my income info in the there i do not wish to start over with a "new" tax return.  Is there a way to re-set the medical section?  I might have hit the button that said, "i do not have more than $5,000 in med expenses  by accident.
