I believe you are speaking of using the TurboTax online version to file this year's return.
If that is the case, then you can log back into your account's Tax Timeline to print a copy of your return by choosing “All Forms And Worksheets”. This should include your Form 8862. You can then save as PDF.
I normally would suggest making sure you have a copy of every form and worksheet used to calculated information that was included on your tax return.
If you remember filling this information out for the Form 8862, more than likely it was filed just not saved as a part of your PDF.
For information on how to print/save your TurboTax return please see link below.

**PLEASE NOTE** If this form was to be included in your return and was not, you may receive an E-File rejection code: IND-046-01 - This will indicate that the form was not filed.
