I assume you had investments under Benefit Wallet. If your Health Equity download does not include those transactions, I can't see how the results would be accurate for you. Capital gains calculations rely upon cost basis from the date of purchase.
My HSA also transferred from Benefit Wallet to Health Equity in March of 2024. However, I did not have any investments under Benefit Wallet. I started them in March under Health Equity, so all transactions are in the download and everything is Short Term for me. The calculator worked for me.
