Given that TurboTax does not support Form 8621, what would be the process I should follow to file my taxes + Form 8621, while still using TurboTax to prepare my forms?

If I had to file Form 8621 but I still wanted to use TT to prepare the remaining forms, how would I go about it?

You would prepare your Turbo Tax return as normal.  Since Turbo Tax does not support Form 8621, you will need to mail your return in with an attached 8621. You can download a copy here to fill out and include with your tax return.

That's disappointing - looks like I'll need to switch from the Turbo Tax product.

Most are moving to Tax Act.  It supports Form 8621.
