I amended my as-yet-unmailed return, but when I download the form to print and mail, the changes are not reflected.

Sometimes the pdf on your homepage can lag behind when you make changes to fix a rejection/do an amended return.

You can print out the most recent copy of your return using the steps below

• Log into your account
• Click Taxes and then My Tax Timeline
• This should bring you to your 2016 tax information
• Scroll down on the page until you see "Some Other Things You Can Do"
• Click "Add a State" (you aren't going to add a state but this will let you back into your return)
• Click My Account and then select Print Center
• Follow the prompts and you will be able to download and print the return that has your corrected forms.
