Filed extension using Easy extension and paid estimated taxes paid, now using turbo tax desktop to file, I don't see options how to pay/refund the difference

Hi,

I filed for extension using the easy extension, and paid estimated federal taxes. Now I am using the turbo tax desktop to e-file. Now I see the actual federal taxes I owe is lower than the estimated payment I made in April. I don't see an  option to enter my previously paid estimated taxes and get a refund back. Appreciate help - Thanks
