Yes. You missed the window to sell the home and get the principal residence sale exclusion. You had to have sold it by 12-31-18. The rule is that you must have lived in the home for at least 2 of the 5 years prior to sale.
You could back in for 2 years and that would reduce the taxable capital gain, not eliminate it (the rules are different depending on whether you lived in it before or after renting it)
