I'm sorry, but you are exactly right. Based on the message you so thoroughly shared, this issue has been identified by TurboTax as a "bug" that will be fixed on April 30th. This year, I had a similar rejection notice (never received one before) and had to wait until 2 days ago for the fix. At that point, I was able to successfully e-file without any issue.
I'm sure that the extended deadline has allowed TurboTax to take a little more time to fix these issues. If this is the only issue you have with your rejected return, you should be able to file after the 30th without a glitch.
Best of luck!
