Please only anser question e and f, thank you!

Undertones, Inc. began 2018 with the following balances in deferred tax accounts: DTA - Valuation Allowance $5,000 (CR) Deferred Tax Assets $175,000 (DR) The deferred tax asset results from a balance of $500,000 in the Estimated Liability Under Warranty. The deferred tax liability results from the financial accounting bases of depreciable assets exceeding the tax bases of depreciable assets by $320,000 due to excess MACRS depreciation over straight-line in previous years and an Installment Receivable of $40,000 that will be collected upon and taxed in 2018. Pre-tax accounting income in 2018 and 2019 is $25,000 and $130,000, respectively and includes non-taxable municipal bond interest of $75,000 in 2018 and $50,000 in 2019. During 2018 straight-line (financial) depreciation exceeded MACRS (tax) by $35,000. In 2019, MACRS (tax) depreciation exceeded straight-line depreciation by $40,000. In 2018, Undertones received $30,000 in unearned revenue which will be earned evenly over 2019 and 2020. In 2018, Undertones incurred actual costs to repair products associated with warranties of $475,000, though warranty expense was $137,000. For 2019, warranty expenses totaled $250,000 and costs repair incurred under warranty were $205,000. Undertones also insures the life of its president, Feargal Sharkey. Premiums of $15,000 were paid in both 2018 and 2019 and Undertones is the beneficiary on the policy. Deferred Tax Liabilities $126,000 (CR) At the end of 2018, management estimated that the DTA - Valuation Allowance account should have a balance of $12,000. Undertones' management decided that at the end of 2019, the valuation allowance should be 5% of the Deferred Tax Asset balance. The tax rate was 35% for 2017 and 2018, but during 2018 Congress changed the applicable tax rate to 21% for 2019 and all subsequent years. In the event of a net operating loss, use the new tax rule under the TCJA related to NOLS: NOL carry forward and 80% limitation.
