BillM223, per your question, I had single HSA coverage for all 12 months of 2024 and did not make any other contributions to my HSA besides this one-time funding distribution.
The 1099-R form in question (with distribution code G) is from Vanguard and I doubt they will be willing to provide a corrected version.
Another workaround I found from an earlier post is to manually zero out the line 1a amount (Less: Amounts rolled over) in the 1099R Summary Form (but keep the line 1f amount (Less: HSA funding distributions)). This results in a correct Form 8086 (line 7 is 0). However, doing this prevents eFile, so I would have to mail in my return.
@BillM223 and @dmertz , does this sound like a reasonable workaround?
