How can I add the forms the irs need Which is the1095A and 8862

You can add this by going to the Health Insurance Section. The 1095A should have been sent to you by the MarketPlace. If you have not yet received your 1095-A, please contact the MarketPlace at 1-800-318-2596.

You said the "IRS need" these forms, so I'm assuming that you have already filed your return and have now received notification from the IRS. 

If they are not requiring you to amend the return, but rather to send them these forms:

1.  Sign in to your account with the same login you used to file your return.

• If you can't remember, go here so we can help you get log in.

For the Form 8862:

1. While in your return, click on the Federal Taxes tab
2. Go to Deductions & Credits
3. Scroll down to you and your family and click edit/update/revisit next to Earned Income Credit (EIC).
4. Answer "yes" you want to work on this credit and hit continue
5. On the screen that asks "Do any of these uncommon situations apply?" check the box next to "We got a letter/notice from the IRS telling us to fill out an 8862..." continue following the onscreen guide.

Once you have completed these steps, you will now print your return and follow the instruction you have from the IRS to submit these forms to them. 

To print your return, click on "My Account" at the top, then "Print Center", next, click on " Print, save or preview this year's return".

If the IRS notified you that you need to amend the return then to amend the return follow these  instructions. Once the amended process has begun, follow the above steps to include these forms into your return.
