Get your taxes done using TurboTax

I E-filed last night 4/2/2020... I ended up having to pay because I believe my income was miscalculated.. The additional income is from social security . I am 66 years old and eligible for full retirement. I understand I could not make more than $45,000.  from July to Dec 2019. As you  can see by my return I didn't come close. This income is therefore non taxable if I am not mistaken. Therefore, I do not believe I should have to pay. What do you think?
