@AnnetteB6, As you noted with underlined and italicized text in your reply, " It is very important that you do not revisit any other section of your return before you file or the change may not be retained or able to be changed a second time."
That is not a solved problem. That is a work around defective software. I'm still wondering about my prior post in this thread where I pasted a screen shot of the accuracy guarantee. What does that guarantee provide to me if the software defectively calculates the $300 or $600 credit? Even if someone manually fixes the program's inaccurate number, then they must be real careful to never "revisit any section of [the] return" before filing. What? You imply that an inaccurate program, that subsequently can't be used without breaking a manual work around, is normal. Uggh...
