Tossefta sur Le Deutéronome 26:1

וְהָיָה֙ כִּֽי־תָב֣וֹא אֶל־הָאָ֔רֶץ אֲשֶׁר֙ יְהוָ֣ה אֱלֹהֶ֔יךָ נֹתֵ֥ן לְךָ֖ נַחֲלָ֑ה וִֽירִשְׁתָּ֖הּ וְיָשַׁ֥בְתָּ בָּֽהּ׃

"Quand tu seras arrivé dans le pays que l’Éternel, ton Dieu, te donne en héritage, quand tu en auras pris possession et y seras établi,

Tosefta Bikkurim (Lieberman)

First fruits are not presented before the Pentecost festival, as detailed in Mishna Bikkurim 1:3 and other references. However, if these fruits were presented before Pentecost, the individual is required to wait until Pentecost to recite the confession in the presence of a priest, as indicated in Deut. 26:1.
