Import 1099-B into Cash App Taxes (formerly Credit Karma Tax) via CSV
// credit_karma_1099B_csv.js
// copyright Phillip Marshall 2019-2025, except lines 28-29, with help from kirill578
// --- README ---
// Cash App offers a free tax filing service (formerly under Credit Karma's brand),
// but requires you to enter Capital Gains and Losses manually in 'Spreadsheet entry' mode.
// This script implements the missing CSV import feature for 1099-B gains and losses.
// The csv this was based on came from a wealthfront xls, exported with mm/dd/yyyy dates and NO HEADER.
// Here are the first few lines from mine so you can make sure yours lines up:
// "2 ISHARES TR NATIONAL MUN E TF",01/30/2017,03/13/2018,216.7,216.72,,0,-0.02,Long-term
// "2 ISHARES TR NATIONAL MUN E TF",Various,09/14/2018,216.12,216.27,,0,-0.15,Long-term
// "1 ISHARES TR NATIONAL MUN E TF",03/09/2017,09/20/2018,107.7,107.72,,0,-0.02,Long-term
// "1 ISHARES INC CORE MSCI EMKT",03/08/2018,04/09/2018,57.53,58.61,,0,-1.08,Short-term
// "1 ISHARES INC CORE MSCI EMKT",11/28/2017,04/24/2018,57.07,57.16,,0,-0.09,Short-term
// And the original header, since I removed it...
// "Description of property","Date acquired","Date sold","Sales price",Cost,Code(s),"Amount of adjustment","Gain (Loss)","Holding period"
// To use, paste the whole script into your developer console when on this page:
// https://taxes.cash.app/r/capital-gains/spreadsheet
// A button will appear at the top of the page to select your CSV(s).
// Pick it, and the form will fill itself out.
