Can you explain this error "Check This Entry Schedule CA: SW Line J Write in text must be entered."

[CoconutWater1]

• Why is the description for line J blank?
• And why am I required to type in the description?
• What do I type in for the description?
• Why is line J prefilled with 700? And its greyed out so I can't change it?

Check This Entry - Why is Line J blank? Where is the 700 number coming from? - CA state tax return
