Can't switch from freefile to regular on turbotax

I filed for an extension ij July and am trying to finish but I am having major trouble with the site. I must have filed for the extension under IRS Free File program but now that I've entered my info I don't qualify. That's fine, I'll switch to the paid service but there is no way on the Turbotax site to do so, it just wants to send me IRS.gov.
how do I switch to regular Turbotax and keep the information I've already entered?
