Hi @TurboTaxStdUser,
I just had the same issue that you did. After looking online for a long time and then eventually reading the fine print instructions on Schedule 15 in Forms view, I realized that the entirety of Step 1 should be blank if the FHSA account was opened in 2024 (like mine was). I had the year 2024 input, since that is the year I opened the account. However, since I didn't open anything in 2025, this should be entirely blank. After removing the year, my NETFILE error went away!!
Hope this helps!!
