The gemara says that the korban toda could not be brought on 14 nissan because some of the loaves are chametz and we only have a few hours to eat them. Couldn't the reason given be that some of the loaves that were brought as part of the toda are mataza and they couldn't be eaten at all on 14 nissan because of the issur of not eating matza on erev pesach?

1) The Tziyon LeNefesh Chaya here (TzaLaCh); written by the author of Noda biYehuda; writes (just before the paragraph in Tzalach that begins with the words Tosfot DH Ein Mevi'in) that since there is only a Rabbinical prohibition against eating Matza on Erev Pesach, whilst there is a Torah Mitzvah to bring a korban Todah, it follows that the Rabbis did not apply their prohibition in a scenario where doing so will mean abolishing a Torah Mitzvah.
2) The sefer Rosh HaCarmel on Masechet Pesachim (this was written by Rabbi Eliyahu Margaliyot of Bilgoraj in SE Poland and was published in 1782, so it seems that he was a contemporary of the Tzalach) cites Tosfot below 99b DH Lo in the name of Talmud Yerushalmi that a person who eats Matza on Erev Pesach is comparable to a bridegroom who had relations with his fiancee before the wedding. He is blamed for being impatient, and not waiting till Pesach itself arrives to eat the Matza. Rosh HaCarmel writes that, according to this, there is no problem with eating the Matza loaves of the Todah on Erev Pesach, since one is not doing so because of impatience to eat the Matzot, but rather because of the Mitzvah of korban Todah.
Wishing you a very Happy Chag HaShavuot.
