This can be confusing. You can enter 'Various' by selecting 'Something other than a date'. Check this box and you will be allowed to select 'Various'.
There is no option to select Something other than a date for box 1c. This option is available for box 1b but not 1c. I am using desktop premier on a Mac
Box 1(c) on Form 1099-B is used to report the date a security was sold. You need to choose a date that will indicate if the sale was long-term or short-term. It is likely your Form 1099-B will indicate which holding period applies, if so choose a random date close enough or far enough away from the acquisition date to result in the sale being considered short-term (held a year or less) or long-term (held for more than one year). The only significance of the date is to determine if the sale is short-term or long-term, so pick a date that will give you the correct result.
Yes I know what Box 1c is for. My brokerage statement shows me which assets are short- and long-term, which I can so designate in Turbo Tax; And my brokerage firm tells me the acquisition date is 'Various' for both short- and long-term assets, which again is an option in Turbo Tax (box 1b), so why is 'Various' not an option in Turbo Tax for date sold? My brokerage firm fills box 1c with 'Various'. I counted 213 sell dates. Turbo Tax wants me to create 213 separate fields? The only thing that is important is whether a sale is short or long term. Why bother asking for acquisition and sell dates at all.
