Well you have to check each year from the beginning 2008. Maybe you had a lot of gains that used up the carryover. Did you save the pdf each year with all the worksheets?
Schedule D doesn't actually show the carryover amount. To find your Capital Loss Carryover amount you need to look at your return schedule D page 2. Line 16 will be your total loss and line 21 should be a max loss of 3,000. The difference between line 16 and 21 is the carryover loss for next year.
There is also a Carryover Worksheet showing the carryover from the prior year and the current amounts. Then there is also the Capital Loss Carry Forward worksheet showing the amount transferring over to next year.
In the Online version you have to save your return with all the worksheet as a pdf file to your computer to see Schedule D and the Capital Loss Carry Over and Carry Forward worksheets.
In the Desktop program you can go to Forms and find it in the list in the left column.
