You can still e-file your 2010 tax return until October 15th, 2011. This can be done even if you didn't file an extension. In fact, if you didn't file an extension and are going to face a late filing penalty, it may be reduced if you e-file because the IRS will receive the return sooner.
Keep track of your mileage going to and from the Doctor's office and the pharmacy when you go to fill your prescriptions. You can use this mileage as a deduction if you itemize on your tax return. Keeping a small calendar in your glove box is a convenient way to jot down your medical mileage.
