Pro-Series Professional.  Efiled a 2020 amended return but forgot to change the date to 2022.  It was rejected.  Changed the date and now it won't efile due to duplicate social security number.  We had this same issue last week and my efile person called tech support and they fixed it within 20 minutes.  Called today and the tech support had no idea what to do.  Spent an hour with her on the phone walking through the amended return trying to check the return instead of handling the filing issue.  No issue with the return - it went through once. Same issue as last week- my efile person does not remember what the tech did. to fix the duplicate SSN issue.  Any one have a clue?
