Yes, something in last year's return is triggering an action in the software.
The issue could be with Form 1116. The Simplified Method is triggered when the Foreign Tax Credit is claimed without Filing form 1116. There is a penalty for this: you can't claim a carryover of the credit from prior years. If TurboTax doesn't see this form, it thinks you "elected" the SM.
When you imported the tax return, either the form isn't present, or something is causing a hiccup. This may not be the problem, so your best option probably is to restart your return.
Please follow these instructions to clear your return and begin again.
