Charitable Contribution default error

In filing my Federal/State return, there is an error message during the Analyzing Review, which states my Charitable Contribution is an unacceptable amount. The software defaults to $300, and as Married filing joint, the Charitable Contribution should be $600. No matter what changes I make to the worksheet, the software defaults to $300 and I'm unable to completely file my E-filing because of this error.  Is there a software fix pending?
