無攝太歲, honestly it is not very big deal unless you are very superstitious and you did these all the time. Otherwise, live still goes on everyday. It is just the thoughts, we always say if you have a good heart and you do thing with your good heart, every bad things will go away silently.
If you really want to do it 攝太歲, you can go to any temple and give some money and they will help you to do it. Good luck
