Ok. I just spent 3 hours and $79.99 on turbotax talking to support and tech help. The ‘other income’ is MOST LIKELY CERB, which is considered income. The problem in this case is that you have probably either a) done your taxes more than once out of frustration, and not erased your previous returns so the ‘other income’, or your small CERB amount keeps adding up. Or b) you have collected several CERB payments which has added up to thousands of dollars.
CERB, FOR THE AVERAGE PERSON, WILL BE YOUR ONLY SOURCE OF ‘OTHER INCOME’. Unfortunately it IS income.
So if your ‘other income’ doesn’t equal the amount of CERB that is on your T4A, make sure you properly and fully erase all 2020 tax returns and start again. CERB will appear as your ‘other income’ again but it should match your T4A this time.
*Happy note-if you made under $38,000.00 you won’t have to pay your CERB back (unless you REALLY milked CERB). But you DO have to pay about $400.00 income tax on each $2,000.00 payment.
I hope this helps someone puzzled over ‘other income’ as I was.
