The tax transcripts from the IRS just take 2-3 days. They want to make sure you have filed your 2014 tax returns and aren't just providing them an unfiled tax return. Being 1099'd, you are considered self-employed, and lenders require 2 years of tax returns reflecting you are self-employed. Loan officer should have known this ahead of time, fortunately it sounds like you have fixed the situation so it's just a matter of time for underwriting to review and verify the 2014 tax returns have been filed and then you should be good to go.
P.S. You can reply to people here, but none of us will ever get a notification you have replied because Trulia has disabled that feature. If you have follow up questions I recommend you contact the person directly by clicking on their picture and sending them a direct message.
