For what it's worth as of 4/6/20 the errors in computing 8615 worksheets still persists! Having much the same experiences as others have related and talking to various CPA in the TurboTax service as well as IT professionals that swore it was fixed; they still speak with out fixing the issues. I have resorted to looking at the IRS latest instructions for 8615 and found that the IRS updated their package for CY2018 and called it CY2019 ( forms inside didn't roll the CY correctly! ugh!! rev=Feb 2020) Seems like everyone is afflicted with issues? Long story short; I manually hit override serval place in the worksheets as suggested earlier and viola! It was accepted when electronically filed thru TurboTax.
