did you pay enough in estimates.
there should be no underpayment penalty if any of these apply:
1) 2020 taxes less withholding are under $1000
2) 2020 withholding and timely estimated tax payments are 90% of 2020 tax
3) 2020 withholding and timely estimated tax payments are 100% of 2019 tax (or 110% if your 2019 adjusted gross income was over $150,000, $75,000 if married filing separate)
