What do you want to type? Copy and paste here the Japanese text you found in the translator. Don't forget that there's no kanji keyboard, only plain hiragana/katakana alphabets here. I'll show you the 4 screens for all the alphabets. The first thing you'll see when you tap the ア icon next to A and heart is this screenshot, the basic katakata mode. You can type "アメリカ" (America) right here.
