I have invested HSA funds into Mutual funds and other stock options available thru my HSA provider I live in California and I have to report my total gain and loss. How can I calculate my total gain and loss as there is no such report is available from HSA Provider?
If there is absolutely no report available and you are certain that you have tried all you can to obtain one then you will need to make your best educated guess as to what has caused the growth in your HSA.
Hopefully they told you what you were being invested into so you have the ability to calculate growth in interest or dividends or capital gains. If you unsure of that then to be safe just declare it all as regular income and make notes about what you've done in order to keep track if any questions arise.

@RobertB4444 , California does not recognize HSAs. The dividend and capital gains distributions paid by funds held in the HSA have to be reported on the California tax return as additions to income. The amount that needs to be added is the amount that would have been added to federal income had the funds been in a regular brokerage account instead.
