My tenant said she’d be staying another year. Now she’s giving me 2 months notice. What can I do?

If the tenant had a one year lease and it has expired, the tenant is entitled to remain on the premises on a month to month basis under the same terms and conditions of the original agreement. In the absence of documentation showing that the tenant has agreed to rent the unit for an additional year, the tenant can terminate the tenancy on 60 days written notice.
