I already paid for state and federal returns at best buy 39.99 and I wont
pay more. how do I get past the last screen
You are posting from desktop Deluxe, not Premier. Desktop Deluxe is sold both with and without state software, so you have to be mindful of which you are purchasing from a retailer. If you purchased the version that did not include state software, that is why you are now being charged for a state download. There will also be a fee to e-file a state return ($24.99) but you can avoid the state e-file fee by printing, signing, and mailing the state return.
Examine the packaging from the the software you bought at Best Buy and see if it says it includes a state program.
Or another thought. Did you fill out the state return and trying to efile it? There is a 24.99 fee to efile a state return from the Desktop program. Then to have the 24.99 fee deducted from your refund there is an Extra 39.99 Refund Processing Service charge.
I ask because currently it is 44.99 to buy a state program download not 39.99.
