Hold it---what do you mean by "my divorce finally ended?" If you were still legally married in 2019 your filing choices are married filing jointly or married filing separately. You cannot file as Single until the tax year that you actually became Single. Or if you were apart for at least the last six months of 2019 and were the custodial parent of the children you might be able to file as Head of Household. Be careful about the filing status you are using on your 2019 return. If your divorce did not become final until 2020, your 2019 tax return status cannot be Single.
Online tax preparation and e-filing for 2019 returns is now permanently closed. You had until midnight on Thursday, October 15, 2020 to finish and attempt to e-file; if your e-file was rejected you had until October 31, 2020 to make corrections and re-file. Now it is too late to use online software or to e-file. If you have any changes/corrections at all to make to your 2019 return, you now have to complete it using desktop software, which you must download to a full PC or Mac (not to a mobile device).Then you need to print, sign and mail it.

If you are getting a refund, there is no penalty for filing late. If you owe tax due, then file and pay the amount due as shown on the Form 1040, but expect a bill later from the IRS for the penalty and interest you will owe. Only the IRS will calculate this—TurboTax will not calculate it.
