How do I add other taxes from form 8621 to Schedule 2 in TurboTax Online?

I have additional taxes calculated on a form 8621. How could I add them to a Schedule 2 on TurboTax Online? The Other Taxes section does not have an option for taxes from a form 8621.

The only method is to enter this manually in Form 1040/1040 SR worksheet.  For this, you need Turbo Tax Desktop. In desktop, go to the forms mode. On the forms in my return, go to 1040/1040 SR WKS, which should be at the top of the forms.

Now scroll down to Line 17 Q.  This is the spot where you will report Form 8621.
