Thank you for your response. I am using an online Premier version of Turbotax (which is different from the screenshot that you provided) and it requires that I put some value in the last two fields that you mentioned, otherwise it would not proceed further. And as I mentioned before, it requires to enter at least "1" in the number of days in US for business. ) "0" would not be accepted. It may be some technical glitch, I don't know.
