Thanks for reply. I was on the phone and screen sharing with support yesterday, and they have taken the problem away for investigation. Estimated reply was 7-10 days. I'm using Turbotax Standard Desktop 2018 and my spouse had a net negative self-employment income (loss). The original return submitted back in 2019 accepted this, and in fact the loss is tracked year to year until applied / consumed-out against positive revenue. The REFILE however would not proceed with a negative value for income. The error was immediate and popped up as a dialogue box, along with red flagging the negative value and would not proceed. The support person had me delete unused forms manually from the return, but it did not resolve the error when we again tried to REFILE. Other years have REFILED fine, but not this year when her business began and she had startup outlays that resulted in a negative net income value for that year. I may have to log into CRA and "Change My Return" manually unless the support investigation resolves the error.
