How can I produce a summary of carryovers to the next year?

Yes you can find it in Forms mode.  You can find 2 worksheets.

On the income page The 2023 column shows the carryover to 2024 (not your current loss for 2023).  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.
