Thank you for the reply. Somehow I could not enter into the specific steps detailed. But it gave me a clue as to how to approach and search. Then I muddled through some steps and completed the work. I am unable to verify the exact set of steps since I was not able to find them. However, I am thankful to the clues for a starting point and enabled me get the info into TurboTax online properly.
