Since all tax documents are reported directly to the IRS, you will want to report them on your tax return. If you are expecting more tax documents, then you should wait until you have them to amend your tax return.
First, you will want to wait until your tax return is accepted or rejected. If it is rejected, then you can go in and fix the mistake. If accepted, then you will want to wait until your original tax return is processed by the IRS. If you are receiving a refund, you should wait until the check is issued. Amended returns must be filed by mail.
