Get your taxes done using TurboTax

I didn't really understand how to do multiple payments by different methods.    On my online account with the IRS   -  I need to first pick a payment method (bank or credit card )  and then can split it to 5 payments ...  but still all 5 will be of that same method , right ?  
   it says :   "You may include up to 5 payments per transaction and submit up to 4 transactions per day."   

So -  do I need to do it in 2 separate transactions ?  (i.e.  one transaction paying by bank account and  another transaction paying by credit card ?   )  will that be OK ?  
PS:  I filed  with turbotax  about a week ago asking to pay by check , as was recommended here , but   I still don't see the balance I need to pay on my online account with the IRS ,  so - which payment type should I chose ?   :

-  2024 Income tax 
  or 
- pay towards your balance 
?
Thanks,
