Where is the source or input button

[Debbarr]

I purchased the QN55Q7FAAFXZA QLED TIZEN. I added an external antenna. All went well and scanned and loaded multiple stations on Air Tv. When I go to use it it only shows Samsung TV Plus stations. I cannot find a source or input button on my remote or in settings on this TV.
