On my 2015 consolidated 1099

[iouwhat]

i show a loss of $4483 which I never submitted. Can I use that loss to offset this year's gain?

No, this must be used on the 2015 tax return and if there is any loss that is limited you can carry over the balance to 2016.  

To amend your tax return use the information below and be sure to read it completely before you begin so that your original figures are entered on the amendment appropriately.  The IRS does not allow the amended return to be e-filed therefore you must mail the return.  Instructions will be provided including the address. Your state return should be included in the amendment if applicable.  (see images attached)
