Worked for me.
Did you make or log in to your "myturbotax.intuit.com" account? I did, for paying that State filing fee. Might help.
Were there any errors that TT noted? I found there were errors from uncompleted boxes on the "Child and Dependent Care" deduction and credits page, which didn't apply to me. I had to explicitly go through the interview QA and select "No", "No", "No", etc. to effectively remove the non-applicable form.
Do File/Save and look at the PDF output, to make sure there are no un-necessary forms.
WiFi is stable? No other streaming video or bandwidth-consuming tasks on the line?
Browser settings preventing secure (https://) connections to the intuit server (ttlc.intuit.com)?
