That's really a question YOU should ask Intuit! This board, like the name implies, is a community board of preparers who often take time during their busy days to try to help other preparers with answers based on their previous experiences and knowledge.
Intuit is the middleman. If IRS wants to allow the first payment on July 15, then it will allow Intuit to transmit returns with that instruction. If, as is more likely, Congress wants IRS to allow the first payment on October 15, the program will be changed to do that.
Rule 1: Don't sweat the small stuff.
Rule 2: It's all small stuff.
