Hello Beckyjc2000,
Welcome to the Community page,
If you don't have MTD turned on you can click prepare return and then you will be able to enter the start and end date. as long as no other periods are filed in Quickbooks, by the sounds of things it doesn't sound like you have. Then once that first period is filed the next period will start the day after the end date of the filed period.
Then once you are all up today to the period that it is showing you currently. if you turn MTD back on then you will be able to submit that return when it is due.
