You will not be able to vacate your plea because too much time has passed. As far as expunging the record that will not be possible if you were convicted as part of your plea bargain.
The only way to seal or expunge your record is if you received a withold of adjudication (withold of the conviction). You need to check and see if you were convicted.
The fact that you were inside your house will not help you in overtirning your plea.
If you are satisfied with my answer please do not forget to "accept" it.
