Sleep well tonight because this is not an issue you need to worry about. This is not a bar to adjustment of status for an immediate relative of a US citizen. You do not need a lawyer for this.

B. Immediate Relatives
Certain adjustment bars do not apply to an immediate relative, including the spouse or child (unmarried and under 21 years old) of a U.S. citizen, and the parent of a U.S. citizen older than 21.[2]
An adjustment applicant applying as an immediate relative may be eligible to adjust status even if:
The applicant is now employed or has ever been employed in the United States without authorization;
The applicant is not in lawful immigration status on the date he or she files the adjustment application;
The applicant has ever failed to continuously maintain a lawful status since entry into the United States;
The applicant was last admitted to Guam or the Commonwealth of the Northern Mariana Islands (CNMI) as a visitor under the Guam or CNMI Visa Waiver Program and is not a Canadian citizen;
The applicant was last admitted to the United States as a nonimmigrant visitor without a visa under the Visa Waiver Program; or
The applicant has ever violated the terms of his or her nonimmigrant status.
In other words, your concern is not an issue...and now, you have an approved EAD....Good luck on the rest of your journey.
