If a judgment of possession was not entered against you by the court, then you can dispute the entry on each of your credit reports by writing to the credit reporting agency and explaining the situation. You can also demand that the landlord remove the credit entry immediately, and if she doesn't, then you can sue the landlord for violating the Fair Credit Reporting Act, for actual damages or $1,000, plus attorney's fees and costs of suit.
If a judgment of possession was entered against you by the court, then it doesn't matter if you obtained a judgment against the landlord, because your credit report accurately discloses the judgment.
In which case, you might want to negotiate with the landlord, by offering to remove the judgment against her from her credit report, in exchange for her removing yours.
Assuming she agrees, you could each file a motion to set aside and dismiss judgment in each of the preceeding cases, and the other party could consent and then the credit reporting agencies would automatically delete the judgment entries on your respective reports.
That about covers the possibilities. Hope this helps.
