Okay Payroll Gurus...never have had this happen before - in 30 years, no other client of ours has done this. We had a client on v2017 who ""mistakenly"" used an 09/01 date on her checks and as her payroll date, instead of 10/01. She had already printed her quarterly reports and done her filings for the 3rd quarter, prior to running that payroll dated 09/01. But she obviously did that 09/01 Payroll before she closed her 3rd Quarter. While her YTD totals are correct - all of her Fourth Quarter Reports are off because she's missing that 10/01 Payroll. Before calling us, she changed her Payroll setup back to Q3 as the Current Quarter, reversed the Payroll, changed the current Quarter in the Setup back to Q4 (obviously without doing another close - thankfully), and posted that Payroll with a 10/01 date. Since there is only one ""bucket"" for the Quarter, the end result of the reversal and the re-entry was that nothing changed in the totals for Q4. I advised that since her YTD totals are correct, her W-2's should be correct, but she would have to do the calculations for her 4th Quarter Reports by hand, manually adding in that erroneous check run that should have been dated in Q4 and not in Q3. Obviously the other option would be to restore her Q3 from a backup before she closed, and recreate all of the payrolls since, or use the ""Fix"" button and change the Quarter Totals for each employee. Which still won't affect the 941 - but am I missing anything else?
