Thank you all for your help. After wandering around these forums for a while, I discovered a thread that clearly describes my issue, along with the work-arounds or solutions for it. Here is the thread:
https://ttlc.intuit.com/community/state-taxes/discussion/re-when-claimed-as-dependent-state-1040-dis...
I agree with the opinions expressed therein, that TurboTax's messages related to this issue should be made clearer, before an unwary user ends up mailing in an incomplete state return.
Thanks again; have a blessed day!
