I purchased MAX Defend and Restore for my 2018 tax return. I've just gotten a CP2000 from the IRS for those same tax returns. TurboTax should honor my purchase, right?

According to the IRS I underreported revenue from a home sale.  However, the house was my primary residence for over two years before I sold it and I made less than $250,000 in profit from selling it. Why did I get a CP2000?

Did you get a 1099S for the sale?  That would explain why they sent you a letter.

I RECEIVED A LETTER FROM THE IRS/STATE

TurboTax does not receive any information from the IRS or your state after your return was filed, so no one at TurboTax knows about a letter you received from the IRS or the state.

TurboTax has a special phone number for help with IRS/state tax letters, which will be easier than going through regular Customer Support.   At the page below, click on the blue button that says "Get Help from TurboTax Support".  Then it will ask you what tax year is your letter.  Then it will ask you what the letter concerns. Then it will show you the phone number during posted business hours.

If I was sent one I never received it, but I'm doing my best to see if I can retrieve one from 2018 right now.
