I see this question has been asked in previous years but it seems the answer has always been "no, you need to print out your return and mail it in with your statement". I'm hoping this has changed for TurboTax 2015. Thanks.
Unfortunately, no, you cannot add any attachments to your return. If you need to attach something, you will have to file by mail.
Re: Is there a way to attach a statement to my efiled federal and state tax return for tax year 2019??
No, you cannot add any attachments to your e-filed return. If you need to attach a statement, you will need to file your return by mail.
No. You cannot attach a statement to an e-filed return. If you need to attach anything you can print and mail your return. For information on how to print and mail your return, please click the link below.
Why is Turbotax so stubborn in refusing to add this capability. TaxAct has had this feature for many, many years. Also I believe that Turbotax Professional version has this feature. So there is absolutely no technical reason that it can't be implemented.
