question about the 4605t form

I am self employed and recently was recently pre approved...or I guess more so pre qualified because the only information they asked was income...pulled my credit...and asked about my employment and how long i had worked there. But my real question is about the 4506t form. I signed the form but when doing so the loan officer told me that they normally dont request for the transcripts that only if there was an audit. I am suppose to close on the 12th and i am super stressed out about it. I gave them a copy of my tax returns signed by my Cpa. But since then after talking to my cpa who has been doing my taxes for years....I found out that the wrong income was filed to the IRS. We went back over the numbers and apparently some of the invoices of money that was mad was not filed. I will have to amend my taxes regardless but i really do not want this to affect the outcome of this loan. I really do not know what to do?? My loan package was turned in this past Tuesday and I have still not heard anything. I am suppose to do the walk through on the home on thursday. If you could shed some light on this situation i would be more then greatful! Thank you!
