It depends on why it's being held. How are the payments being made? Does it show that it's expecting you to ship something, or are they being paid with "no shipping required"?
As for changing the account type, what you are doing is actually a business. You should treat it that way, and leave the account as a business account.
Claim the income you're receiving here, and pay any tax you may owe on it as you should. This will also allow you to claim all of the available deductions you have a small business owner, which are many. You will be much better shape if you just treat this as a business like it is.
To answer the question, though, you cannot downgrade an account. If you want a personal account you will need to create a separate one.
