Thank you @GeorgeM777 for answering my question considering my unique scenario. I have contacted my employer to understand about reporting the option exercise on my W2. However, in either case, I don't see an option on Turbotax to specifically report the exercise of NSO. Whatever will be reported on W2, will be the final taxable income, but I couldn't find any tab on Turbotax for entering NSO grant and exercise details. In this case, I can only go with whatever my W2 says (irrespective of whether I get a corrected W2).
