I found new dictionaries sites. I'll share these below.
- Dil Derneği (means “Language Association”): This dictionary's homepage is http://www.dildernegi.org.tr/TR,274/turkce-sozluk-ara-bul.html. But I don't find search engine URL
- Kelimeler.gen.tr (means “Words.gen.tr”): https://kelimeler.gen.tr/sozlukte-ara?q={searchTerms}
- Nedir Ara (means “What is it? Search”): https://nedirara.com/{searchTerms}
- TürkçeSözlük.net (means “TurkishDictionary.net”): https://www.turkcesozluk.net/index.php?word={searchTerms}&sozluk=turkce
