Turbo Tax Online (and I think most Online self prepared tax programs) close down soon after the Oct 15 extension deadline to get ready for the next year. You have to submit your efile by Oct 15. If it rejects you had until Oct. 20 to fix it and resend it. Then Efiling is permanently closed for the current year.
Check over in the QuickBooks forum. Maybe there is a way to convert your QuickBooks Self Employed version into a Desktop QuickBooks program so you can import it to the Desktop Turbo Tax.
