I am a US and Canadian citizen living in the US. I received OAS payments from Canada (T4), as well as a $500 Covid senior payment sent to all over 75 OAS recipients (NR4), none of which had anything witheld. I received nothing else from Canada. It seemed to me all I had to do was convert to USD and add to my US Social Security. The total would be less than $2000. However, previously I used a tax professional who just retired and he always included a form 8833 which simply said I was a resident of the US and OAS would be reported as social security income. Do I really need to do that? It's obviously more work since Turbotax doesn't support that form. Thank you.
