The IRS is questioning my earnings for 2018 is there a way I can get your help on this since I did file it with turbo tax

If you did not purchase the optional Audit Defense product, you can phone TurboTax free Audit Support Center for help with an IRS letter.   At the page below click the blue "Get Help" button and follow the prompts to get the phone number.

If you explain more about your situation in this user forum, you may get some suggestions here, too.  But this is a public forum, so don't post any personal info.
