We just encountered the same Proseries Glitch! College Dependent (now age 20) was being calculated as a qualified dependent for the EIP1 and EIP2 giving the taxpayer an additional $500+$600 ($1,100) in rebate recovery which is not accurate. We think this is because the "child" was under age 17 during 2018.
FIX- we deleted the dependent and re-entered. The EIP1+2 calculation was then accurate
We hope Intuit corrects this glitch very soon!
