Used it for my 2024 1120-S filing. It's not compatible with online QuickBooks, really Intuit? I explicitly followed their instructions to download the QB desktop application (30-day trial) and the migration tool. After about an hour of working out the kinks, I was able to successfully import data from my online QB account. But in reviewing the file, the P&L and Balance Sheet were way off. Turns out they were missing many transactions and were wildly different from the Online version. I began to try to resolve the differences but quickly realized it was a futile exercise that would've taken me longer than manually entering everything in the program - so that's what I did.
