The 110% rule is not just for SE ... if you enter what the 2019 tax liability was and the amount you paid in estimates then there should be no penalty id you paid the estimate evenly throughout the year. If you did not then you need to complete the 2210AI form to reduce or remove the estimated penalty. The Program follows the IRS rules on this subject so you can pay more than needed for the safe harbor method but still owe an underpayment penalty.
