Hi, welcome back.
I got my answers. TSH level is definitely increased significantly above the normal level. As you have undergone total thyroidectomy it is necessary to continue thyroxine supplements. Thyroid hormone are necessary for body. In addition that you are on low iodine diet which is again causing increase in TSH. Had you stopped drugs after consulting with physician or your own?
You need to consult your physician or surgeon again for proper adjustment of dose.

Hope I have answered your query. If you have further concern, please let me know.

Regards.
