I was out of status for alot longer than you and only filed the 485, not 485-A. I was interviewed and wasn't even asked about being out of status. Per USCIS website, 485A refers to:
Section 245(i) of the Act allows certain aliens to file for adjustment of status upon payment of a penalty fee of $1,000, even though
some of the conditions required by section 245(a) and (c) of the Act are not met. Aliens in the United States who have an immigrant
visa immediately available, but who entered the United States without inspection, remained in the United States past the period of
admission, worked unlawfully, or are otherwise ineligible for adjustment of status under section 245(c) of the Act must submit this
form along with Form I-485, Application to Register Permanent Residence or Adjust Status.
I'm no lawyer. You can always call USCIS for clarification.
