If you need to submit certain forms (or attachments) with your return, you are still able to electronically file. However, you will need to complete and mail in Form 8453 U.S. Individual Income Tax Transmittal for an IRS e-file Return along with the forms or attachments.
1098-C - Contributions of Motor Vehicles, Boats and Airplanes (or acceptable documentation/required donor documentation)
2848 - Power of Attorney and Declaration of Representative
3115 - Application for Change in Accounting Method
3468 - Computation of Investment Credit (if historic Structure Certificate is required)
4136 - Credit for Federal Tax Paid on Fuels (if certificate and/or reseller statement is required)
5713 - International Boycott Report
8283 - Non-Cash Charitable Contributions (Section A if statement(s) required or Section B, appraisal section).

8885 - Health Coverage Tax Credit, and all required attachments

Note. If you have a Form 8949 attachment, you will simply enter the summary totals for each reporting category into TaxAct. If you have a PDF version of this attachment, you will be able to attach the statement to your return during the electronic filing steps.
Any documentation required by these forms should also be attached. If you need to attach other forms, statements, or declarations to your Form 1040 you will need to paper file your return as the IRS will not accept them electronically or with Form 8453.
Do not send Forms W-2 to the IRS with Form 8453, keep them for your records. You will only need to send Forms W-2 with the return if you are paper filing.
Form 8453 (with the required forms or supporting documents) must be mailed to the IRS within three business days after receiving acknowledgement that the return was accepted. An electronically transmitted return will not be considered complete until a Form 8453 is received by the IRS.
