Turbotax premier not correctly calculating safe harbor for estimated tax

[tiancheng]

Is there a way I can amend the amount manually? 

The amount I owe is 9% of my total tax liability (so I fulfilled the 90% requirement) and I also paid 160% of my last years tax liability (which fulfills the 110% of previous years tax for 150k+ income). I also filled out the Other tax situations > Underpayment penalty section. However, TT is still calculating that I owe underpayment penalty + interest.

It depends. You can print your estimated tax payments and change the amount manually before mailing your payment. Or you also have the option of simply making your estimated tax payments online.
