There is no such thing as "railroad unemployment" and there is only one place to enter a 1099-G for unemployment in the program so I don't know what you entered or where. Look at your return ... the unemployment should have shown up on the Sch 1 line 7. If it is there correctly and you have already filed prior to the change then all you can do is wait. Sounds like the IRS processed the original return and sent the original refund and now all you can do is wait for them to process the correction and send that refund.
If you put the unemployment in the wrong spot then you will need to amend it.
