How to calculate AMT?

I purchased roughly 20,000 ISOs at a strike price of 0.05 per share this year. The FMV of the shares when I purchased was 0.06 per share. I have not sold the shares.

As far as I understand I may owe AMT on that 0.01 * 20,000 ish shares so roughly $200.

I’ve used free tax USA in the past to file taxes but I don’t think im able to report this via free tax USA and I’m trying to determine if I need to pay for turbo tax. I’m mfj and our combined income was under $150,000 for the year. How do I determine if I owe AMT? Do I need to use turbo tax so I can report the purchase of these ISO?
