i sent a check with the amount do on first return; when i fixed error that prompted rejection, it added #2400 to amount due. How do I pay that? Or do I wait for them to catch the shortfall and contact me

I would send a check for the additional amount due.

It might be easiest to set up an account with them.

Thanks. That's what I did; sent in a second 1040 V and another check...with an explanation. they ought to be able to match with original return.
