Yep, it's been a problem before! You can read a previous answer of mine helping somebody else with this same issue.
In short:
You have to change the labels in the header row to be compatible with Deckbox (e.g. Quantity becomes Count).
You have to remove the word "Normal" from the Foil column (originally called "Printing" in the TCGP CSV).
You have to Find/Replace all incompatible TCGP set names to change them to Deckbox edition names.
You have to look for anomalies like alternate art in old sets (Antiquities, Fallen Empires, Homelands, and Alliances) and other special printings.
One thing that I learned since that last post of mine is that you want to delete TCGP's "Name" column and keep its "Simple Name" column (changing its header label to just "Name"). However, before doing that, you can compare the two columns in order to find anomalies like alternate arts. Inserting a temp helper column after column C (Simple Name), then entering the formula =B2<>C2 into cell D2 and copying it down the helper column, and then filtering column D on TRUE values is the easiest way I know of to compare two columns.
Making the edition names compatible is probably one of the more time-consuming aspects. There were several in yours, including all core set names, all promo set names, and several others.
One especially weird anomaly in yours to note -- In 10th Edition, any cards with reminder text had that text omitted in their foil versions, sometimes adding flavor text. So the foils are basically alternates of those cards. However, if you look at the 10E entries in your CSV, those cards aren't marked as foils. Instead, they have a star after the collector number, like 78★ for Dehydration. So for those cards, I had to manually enter in "foil" for them. Note that Deckbox doesn't display the correct foil-specific artwork for them.
I hope the above info plus the attached Deckbox-compatible CSV (fully tested out) helps you! Let me know if you have any questions.
