After you file

Ok ... so this is an OLD payment agreement and not a new one for a 2019 balance due ... would have been nice if you had mentioned that in the beginning.   

 

Now... if the IRS web site says you can log in and check on your account then they are providing false information.   If you are on a payment plan already then you should be able to access info thru the IRS site as they clearly state in their instructions.    If they cannot help you then what can a DIY income tax program and some helpful non TT employees on this public forum possibly do for you.... you are asking the wrong folks for help with this situation.
