Late filing, balance due, can't pay full amount and calculated penalties

[treasur2]

I have a tiny "practice". So limited software experience. Current (not new) client/TP attempted to do her own 2019 at Block. Thought she had filed....but has not. I confirmed after helping her establish tax account access and reviewing with her.

Now, I have 2019 1040 completed. Penalties and interest calculated. However, when attempting to schedule withdrawal of the entire amount. Software only allows (1). Original balance due  (2). Late Filing Penalty for withdraw.

Does not include (3). Late payment (4). Interest.

Why?

Will TP simply get a letter from IRS calculating this (again....but more accurate?)

either let IRS send a bill (which is what I do), or pay it through IRS DirectPay.

Thanks....but ..........why......is this the protocal for the software?

Im just another user, people complain about it all the time, I have no idea why it works the way it does.

I always go with the idea that maybe the IRS will forget to bill the client for those extra rubles so the client wins because of that software feature.

@treasur2 I fill out penalties and interest worksheet with some clients, and system lets me withdraw entire amount including penalties and interest. so you must have some data entry errors. Just go over everything, and pay attention to dates, as they must be same date you are efiling
