Do I need to file a form 926 for an investment in a private UK technology company?

I invested $20k in 2020 into a UK private limited company in the technology industry (non-financial related). Turbotax shows a form 8938 is not necessary because the value of my investment did not exceed $100k (married filing jointly). I own roughly 1% of outstanding shares and did not receive any income from the investment. I have no other foreign investments or accounts. Is a form 926 necessary to file or is Turbotax correct that no reporting is necessary this year?
