I printed Form 8453 and my Form 8949 pages before I e-filed. However, after I e-filed there was a box on the page I then saw in TurboTax that wasn’t clear, but looked as though I needed to do something to finish filing (sorry I don’t remember what it said). I clicked on it and it printed Form 8453 (but not the 8949 pages). So it is an additional step, but maybe not obvious as you were completing your filing and printing a paper copy for your files. You can also go into the forms that make up your file and print Form 8453.
After some research and being a bit baffled by whether I need to send something with Form 8453, having electronically filed form 8949 (the info on Form 8453 might be read to say I don’t need to send anything), I gather it is the support documents for the e-filed Form 8949 that I need to send in. That confusing lack of additional instructions on Form 8453 is an IRS flaw, not TurboTax’s, but it would be a great opportunity for TurboTax to step in and clarify or explain to its users what needs to be filed with the Form 8453 even if a Form 8949 has been e-filed.
