Tax Year Prior to 2020: I changed my filing status and the number of dependents in my 2014 amended return, what type of supporting documents I need to send?

You will send the Form 1040X Amended Tax Return and that's probably all you need to send.  If you removed dependents, that will be fine and the IRS shouldn't ask for anything else.  If you added dependents, and they were claimed by someone else, you may need to prove they qualify for you to take them.  The IRS will let you know what, if anything, you need to send.

Amended returns have to be printed and filed by mail.  It can take the IRS up to 12 weeks or longer to process them.   If you are due a larger refund than on your original return, your amended return should only show the difference and you will receive a separate check for it.  If you owe money on your amended return, it will show only the new amount owed, you will have to mail a check with the return.
