ANSWER:

It’s best to sit in the same spot that you prayed in, but no need to sit in the tashahhud position.

However, no problem if you got up or said the dhikr while walking back home etc.

When we do the morning/ evening adhkar(supplications), do we have to stay in the position of teshehud and be directed to kiblah, or we can offer this dhikr while sitting in couch or in bed or while walking home from the masjid ?
