For what it's worth... I spoke to a TurboTax support person yesterday. He messaged the technical support software group, who said to check back in early February to see if TurboTax updates include the ability to attach the Safe Harbor PDF for e-filing. He said tech support made no promises that it would be available for 2021 returns, but said that they are aware of it and it's on the list of fixes. Seems like they've had a couple years to fix this so not sure why we're still waiting....
Would love to know if anyone knows of any tax prep software that does allow e-filing with PDF attachment, that doesn't require the purchase of a professional version?
