I will be contacting my bank and making sure everything is OK, as well as tax attorneys in my state and CPA's and try to make sure I'm doing everything right.
Your bank and the feds are the only ones you need to worry about, so as long as you get in touch with your bank and tax attorneys you should be fine. There's not much else you can do anyways.
Coinbase themselves probably won't care much about the size of your transactions, as long as you have taken care of the required verification steps and your bank account data checks out.
