I originally asked a question about how to fix an error in our Health Insurance Adjustment. While waiting for a reply, I found the same error in our prior year, and because TT hadn't marked it as an error, I thought it was OK. I didn't get any answers to that original question, but was concerned, so I researched the posts in the Community and found a solution, and made the correction. As it turns out, I completed the request to enter SSA-1099 information in the Business section of our file, but found in my research that the Medicare portion should not be entered there, but later.
Now I need to know if I need to amend prior year(s) if it had the same error? Thank you.
