I filed my 2021 Taxes using TurboTax (download) and have already gotten my return. Unfortunately, I had a partial year (Jan-May) 1099 (DIV, INT and B) from an investment firm that failed to provide me with these forms in a timely manner. This led to an oversight on my part to provide this information. I've looked at your online instructions for amending a 2021 return and am able to navigate to the "Amend a return after it was filed and accepted by the IRS" at the bottom of the home screen. But when I select, I am ultimately taken to a page to select why I am amending the return and there is no option to add a 1099-DIV, 1099-INT or 1099-B. Only 1099-R and 1099-MISC. I've looked at "I need to change me return for a different reason," but none of those options allow me to add my 1099 information. How can I amend my return to add additional 1099-DIV, INT and B information?
