How do i find my 2019 earned income and non-taxable combat pay? i never received an 8812 form or EITC from my accountant?

To find your 2019 earned income go to IRS.gov/transcript.   If you do not already have an account, you may have to create an account.  Once you create the account you will be able to sign in and request a transcript.

To request the transcript after you create an account:

1. Sign into IRS.com/transcript
2. Select the transcript you want. You are going to want your Wage and Earnings Transcript.
3. Select the Tax Year 
4. Anwer the rest of the questions
5. When done you will be able to get a download on your transcript.   

The Wage and Earnings Transcript will provide you all sources of income that were reported to the IRS.  (W2s, 1099-R, 1099-INT, 1099-DIV, etc.)

To verify Form 8812 and EIC, you could also request an Account Transcript and a Return Transcript.    It is done the same as the Wage and Earnings.   One of these transcripts should show if you had EIC or a Form 8812.

How to get my IRS Transcript

If you had an account that prepared your return for 2019, I would suggest you contact the accountant that prepared your return and ask them for a copy of your return and specifically Form 8812 and the EITC.
