1099-B (Cash Certificate)

I have a cash account with my broker that I was using as a Savings account.  I withdrew cash on two separate occasions.  I received a 1099-B because, according to my broker, the cash was held in a cash ultra-short liquid certificate.  The reported loss/gains are $0 so my broker is telling me that I should not see any tax consequences from the movement of that cash.  I'm just not certain how I should proceed.  TurboTax wants to know about the sale of investments in order to properly complete the 8949 form and I don't know what to say here because I didn't sell anything.
