I had the same issue with a spousal return with only $0.2 other income on a T3 on March 24, 2021. I resolved the issue by overriding the no income line to "yes" on the Netfile worksheet and by deleting the T3, i.e. not including it in the tax return. I am not certain that the override is necessary but doing only that did not work.
