Last year I filed using Premier online for capital gains. This year I have a basic return but the online product wants to charge me "Premier" price - how to fix???

I needed to file with "premier" version for capital gains last year but this year I have none, and the "deluxe" version should suffice for a simple return, which I have completed with Online Turbotax - which seems to remember what product I used last time and is trying to get me to pay Premium again. I'm afraid to purchase and input the "deluxe" product code unless I can downgrade this way. Any ideas? Thank you....
