My return is pending hiw can I put in my 1095 form

Once a tax return has been filed it cannot be changed, canceled or retrieved

You will have to wait for the IRS to either Accept or Reject your filed federal tax return.
If the return is rejected you can make the necessary changes and e-file again.
If the return is accepted you will have to amend your original tax return. An amended return, Form 1040-X, can only be printed and mailed to the IRS if the original tax return was not e-filed. The IRS will take up to 20 weeks or longer to process an amended tax return.

Before starting to amend the tax return, wait for the tax refund to be received or the taxes due to be paid and processed by the IRS.

You cannot put anything into a return that is pending.   Do NOT try to change a return that is pending.   If you were supposed to enter a 1095A and did not do so, your return will be rejected when the IRS starts rejecting/accepting returns on January 29.  Wait for the rejection notice and then you can fix it and re-file.
