I have the same problem. TT has a glitch and is not populating the correct amount of $600 for maximum allowed cash donations when itemizing for married filing jointly. It enters $300. I have fixed it on the form, only to have the incorrect amount of $300 return just like others have experienced. And yes, we have well over $600 in cash donations to we qualify. We shouldn't have to do a workaround or override, as that may not allow us to eFile. Turbo Tax, please fix this!
