ProSeries 24 is now requiring W-2s (also in 2023 version) and prior year income to e-file an extension.  These are not required by the IRS to file an extension.  Support is saying the only solution is to uncheck the box to efile the original return.  This was never an issue in the past and needs to be fixed.  We shouldn't have to spend the extra time unchecking the box on every return, filing extensions, and rechecking it to file the return upon completion when it wasn't an issue in prior years.
