the trust, not being a grantor trust - you are trustee and not the sole beneficiary, should have obtained a tax ID # and the 1099-S should have been issued to it. a first and final tax return should be filed, all the income and expenses would be distributed to the beneficiary. you being the trustee are responsible for filing the return.
you also have a problem that now the IRS will have a 1099 with your SSN.
what you need to do is obtain an ID# and file a return as mentioned above.
then you need to file a 1099-s reporting the trust as the actual recipient
from IRS 1099 instructions
Generally, if you receive a Form 1099 for amounts that actually belong to another person, you are considered a nominee recipient. You must file a Form 1099 with the IRS (the same type of Form 1099 you received) for each of the other owners showing the amounts allocable to each. You also must furnish a Form 1099 to each of the other owners. File the new Form 1099 with Form 1096 with the Internal Revenue Service Center for your area. On each new Form 1099, list yourself as the "payer" and the other owner as the "recipient." On Form 1096, list yourself as the "Filer."
