“The only statements that matter are the ones the IRS put out as Guidance”

The only statements that matter are the ones that IRS publishes in the Internal Revenue Bulletin. Those do not include the ephemeral FAQ’s that someone has been composing at home in their pajamas.

“Dependents 17-23 were the real people left out of the EIP plan and provisions are being made on the 2020 tax return to compensate them, if eligible.”

I have no idea what you mean. The only plan I know of is the House bill, which the Senator from Kentucky says is “dead on arrival,” that would change “qualifying child” to “dependent” – I think, both for the first round of EIP’s and the proposed second round. Now that’s what I call wishful thinking, although in politics all things are possible.
