Liquidating equipment

I am retiring and winding down my professional service S corp, will probably fold it in 2022.  I sold about 20 pieces of test equipment in 2021, mostly on eBay.  TT for Business is trying to take me through listing each and every asset, including when it was put in service.  I don't have time for this.  Some things were sold in batches for a single price, and trying to find the dates of first service for all this would be excruciating.  The total proceeds are not worth the trouble.  Is there a way I can simply list the assets as a lump and pay capital gain tax on the sum, or something similar?  I don't need the absolute minimum tax exposure.  Thanks for any help.
