According to the TurboTax Help Article below (which was "Updated 1 week ago" as of 02-11-2025) you can e-file an amended 1120-S in TurboTax Business. The "Amend" function in TurboTax Online is not yet available (expected February 15) so the e-file function for an amended S-Corp may not yet be available either. I would check back on the February 15 to see if it is available.
How do I amend my federal tax return with TurboTax Business Desktop?
Note: You can e-file an amended an S-Corp 1120-S, a C-Corp 1120X, and an Estate or Trust return. You cannot e-file an amended Partnership 1065X in TurboTax Business.
