How much of a long term capital gain can I take without tax?

Filing status is married joint. Using my 2019 figures,  my taxable total income was 44K and my adjusted gross income was 71K. To keep it simple let's say that for 2021 my numbers are the same except I want to add a long term capital gain. I would be able to take a long term gain up to about 36K and it would be taxed at 0%. Correct?
