She has answers, of course. Ones entirely appropriate to the public image of her office - not a hundred percent squeaky clean, but just smudged enough that it doesn't look too much like she's manipulating her records. She has thorough reports even down to who's treated her to lunch, to gifts she's received, not just on campaign contributions or the like. Enough data to give an entire team of investigators a raging headache.
The smudges are... Interestingly placed, more in what's not smudged. (This had been a massive debate among her handmaidens, a massive risk...)
It's not very hard to find out that Damask Holdings of the Intergalactic Banking Clan has its fingers trailing through Naboo's waterways. That Hego Damask had gotten involved in Naboo's politics near the beginning of a young Palpatine's political career. There's grumbles about it sometimes; Naboo doesn't like the IBC and hates Damask even more, and the scandal of King Tapalo's involvement with funding outside of Naboo has dogged him his entire career, and it now looms like a dark specter over his chosen successor, Ars Veruna, in the ongoing elections. That particular association makes the news in Naboo pretty often, sometimes even outside of the planet.
The IBC's money flows like oil through Naboo politics, and Palpatine's office is clean.
These records aren't the ones formally on file, which are mildly outdated and exactly as vague as tax reports by Senatorial offices can get away with - which is pretty vague, given that it's the Senate deciding how much they need to report. These are her internal records, provided to the Jedi's investigators in good faith to prove her office is uninvolved. The smudges link her in a few places to King Tapalo's scapegoats for the investigations into the wider allegations of corruption and criminal conspiracy, but not more than is to be expected given they share a home planet.
(This has every sign of being yet another thing the wealthier corporations will brush aside as a minor embarrassment, legal investigations tangled up in light years of red tape and eventually dying there, the Jedi unable to step outside of the narrow remit the Senate gives them, and a murky pall has hung over the heart of the Republic for generations... Investigations like this fail very, very often.)
