Investing

First of all 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.

 

Then to sell your mutual fund you need to figure out the gains yourself.   Did you buy the mutual fund all at once in the beginning?   Or did you buy shares at different times?  Or reinvest the dividends?   You need to calculate the gain on each share  to determine which shares to sell.  They will have different gains on them.   You might need to make a spreadsheet or list out all the buys.   Maybe the fund company can give you the amounts.  And you have to tell them which shares to sell.  Like the first ones, etc.   But if you bought all the shares at the beginning then the prior answer should be close enough.  But I bet you have been reinvesting the dividends which was buying more shares at different prices.
