Hi, replying on behalf of Anil.
Next step is you will recieve RFE to submit medical exam ( form I-693) for all in your family who applied AOS. If you already submit the exam then your AOS file is documentary completed and your status will change to your I-485 application is approved.
Refer below link for more information.
USCIS will issue EAD/AP card and your AOS application will be only processed once your PD is current again in the future.
They go wasted as the rule is to use all available visa numbers in the same year.
