Get your taxes done using TurboTax

The tax payer filed for an extension on their 2018 taxes. He paid an estimated tax amount, using prior years as his history. This extension needed to be completed in Oct of 2019 but he got ill, needing surgeries and hospitalization and in the end, he passed in Aug. of 2019. As his spouse, I have gathered his files and am ready to file those delinquent taxes, but I'm scared. I think I have all the information. but what if it's wrong. I am working toward getting a home equity loan and in the 12th hour, the underwriter wants to see the 2018 taxes, so 'I'm preparing them myself since I don't have an appointment with our tax preparrer . Is there a way I can contact the IRS and alert them to the fact that I will have them professionally done by the end of the month?
