What should I do if I forgot to show my DTV paperwork upon entering Thailand?

A user recently shared their experience of mistakenly not presenting their DTV visa paperwork when entering Thailand, resulting in them receiving a standard 60-day entry stamp instead. Several commenters provided advice on how to rectify the situation, suggesting options such as returning to the original entry point for correction, visiting local immigration offices for assistance, or using the multiple entry feature of their visa to re-enter the country and activate the correct status. They emphasized that Krabi's immigration services might also be helpful.
