I have never heard of this problem in the last 13 years of answering questions on the TurboTax forums.
When you say your tax liability increases, that would only occur if your taxable income increases or you have Additional taxes from Schedule 1 Line 3.
Where are you seeing on the Form 1040 the increase in tax liability?
On your Personal Info worksheet, Part II, where asked about being claimed as a dependent the answer must be NO. That is the only box in Part II that should be checked.
