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.
Clearly Turbotax programmers and CCRA need to get together and get on the same page as to what constitutes a "0". For Intuit's programmers: Here is CCRA's published explanation:
