I was able to correct Error 25300. This error states that something in the return is forcing the return to open in Forms Mode and it won't allow you go back to Step by Step Mode. We checked to see if a new return could be started in Step by Step Mode. It worked fine, so I concluded there was a corruption in the .tax data file itself, not the software.
First, we checked to make sure Turbotaxx was up to date. Top menu dropdown Online, then Check for updates. Make sure windows is also up to date. SOLUTION: While stuck in Forms Mode, click the top menu File, go down to Electronic Filing, then File Electronically. This cleared the error and allowed us to switch to and continue using Step by Step Mode. Hope this helps!!
