Was that before or after the closure of all but New York? I think since they closed the other offices that NY is a lot busier. I emailed them Wednesday and Thursday and no response yet. I know that its took them two days to open my application after they received it. It also took them two days to approve my visa after I faxed them my criminal records from the courts that they requested.
That's actually really fast, especially as you did not use priority - the NY consulate is currently processing applications at the fastest rate I've seen in the last 5 years!
Back in 2010 when Aquila applied (before the LA and Chicago consulates closed), non-priority applications could take a week or two to be opened and with previous refusals/criminal convictions it could take up to 3 months for processing. In August/September 2010, straightforward (non-priority) applications were taking 30-45 working days, with an extra 2-3 weeks added if you had criminal convictions or previous refusals. As it was, your visa was opened in 2 days and processed in just 17 working days... that's an extremely fast turnaround time considering your immigration record.
Thing is, if you sent your passport back without first confirming that they would accept and correct it and without addressing it to the specific person who will be dealing with it, then I'm not sure that it will actually get sorted out, at least not quickly.
Normally you need to wait for a response from them to find out if you have permission to send it back (whether they are willing to correct it), how to send it, who to address it to and how long it will take for them to correct it.
