I have the same problem, reported to the support team on 18Apr2026, they spent 1.5 hours examining the problem, doing all the things Admin_Susan mentioned, cleared the form, rounded the numbers, still not working. They then got my email and said they would reply my on Mon 20Apr2026. No reply, I reported the problem again. The support agent said someone will email me....nothing rec'd yet, now is evening 22Apr2026. Still cannot Netfile the return due to that error.
The early reply from Anqua which admitted there is an error on their side and then left for good...
Seems like I need to print the return to send by post?!
