hmm not getting any idea. i think the community here also not able to identify that plant either it seems? did you try any plant identification apps? might help you. but i think its too late now. you might have even remove it already.

Close up of leaves? I'm not 100% sold on it being an azalea.

Does look like an azalea. Move in fall after the leaves drop off. Or maybe end of winter if you are colder than USDA 6 (for best results indicate where plants are located geographically when posting questions).

I am in Michigan.

I would move it in early fall, mulch, and water well enough to keep the soil moist but not soggy until it loses its leaves The majority of its roots will be relatively shallow. If its new site is clay, plant slightly high.
