Turbotax Deluxe 2023 - tried to efile 4 states

Dear Turbotax Community,

 

     Unfortunately, I have four state returns to file due to my husband's position as a traveling construction superintendent. When I went to efile my federal with NC, IN, MD, and MI return, I receive a message about only being able to file three states at which point it gives me a back button to uncheck one of the states. Is it a limit on how many at once only?   Or, max limit period with the software?   If it is only at once, do I uncheck one of the states and then I have to wait until my federal is accepted before I file my fourth state?  Appreciate any guidance.
